Nothing there has changed between 5.3 and 5.4. I have even disabled the firewalls on both clients and server but the same problem is present. Another interesting behavior: upon reboot, mount_nfs occasionally succeeds. However if I then go to another client and try to access the NFS server it doesn't work. If I then go back to the first client and try to unmount the NFS partition it also hangs. Viren
